You’d need to check the latest version, but I think that most of the amendments and additions arose from the impacts of cyclone yasi (Qld) as opposed to from any operational safety issues.
Also, when you’ve been involved with the review of Australian Standards (as I have), and considering the numbers of “interests” represented on the panel, it’s quite common for the numbers of additional clauses to be disproportionate to the extent of actual changes to the Standard.
In my opinion, the more important issue is with the apparent autonomy of your Plan’s Strata Manager; your O/C needs to do something about that at the next AGM.
